Installed pylint extension in vs code but it isn't identifying mistakes

Screenshot of what's enabled:

I installed latest version of Python 3.9.4 and also checked it in command prompt it was working well. But as I installed VS Code and also the python extension and made a file in order to check pylint, but pylint is not working even I have enabled it as you can see in image, so what can I do now?

Solution

1.Make sure you've installed pylint to current selected interpreter.

Run pip show pylint to see if it's located in current environment.

2.Check if you set Jedi as "python.languageServer".

Cause if I set Jedi on my machine, the linting won't work. It's recommended you install Pylance extension and in Settings.json set:

"python.languageServer": "Pylance"
